DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling plate made of a transparent glass plate or the like, a fixed wall made up of left and right side plates and a front plate, etc.
A moving wall such as a back plate that opens and closes at least a side opening formed by being opened by an open edge of the fixed wall; and a display device that covers an exhibition space on a base. The base is composed of an upper base body having the fixed wall and the moving wall, a base frame fixed to the floor surface, and a seismic isolation device therebetween, and the moving wall is separated from the upper base body to form an exhibition space. The present invention relates to a structure for preventing the upper base body from being inadvertently moved when taking in and out an exhibit.

[0002]

2. Description of the Related Art Conventionally, for example, in a showcase for displaying an exhibit (exhibit) in a museum or the like, a patent publication of Japanese Patent No. 2709023 discloses an exhibition space formed on a base, At least three of the surrounding walls surrounding the space
In a display case in which the surface and the ceiling surface are constituted by transparent walls, one of the transparent walls is supported by a rail mechanism provided only on the base side, and the transparent wall is opened and closed in a sliding door manner. Wherein the rail mechanism is arranged substantially horizontally, rail holding means for holding the rail so as to be able to protrude and retract by parallel movement on a base, and substantially horizontally guided by the rail. And a moving block capable of moving the body in a direction, wherein a portion near one side of a lower skirt portion of the transparent wall is fixed to the moving block.

[0003] When such an exhibition device is directly fixed to the floor, the whole of the exhibition device may roll over due to an earthquake or the like, and the exhibit may fall down and be damaged. The installation of the display device through is performed.

[0004] This type of seismic isolation device uses a base frame fixed to the floor surface, utilizing the fact that an article above a heavy base or the like has an inertia that tends to stop against rolling on the ground. It has been considered that an upper base body is mounted on the base via a seismic isolation device, and the upper base body is provided with the fixed wall and the moving wall.

8b is pivotally connected to the middle of the one link piece 28a.

The intermediate vertical plate 20 is provided between the outer surface of the vertical plate 21 fixed to the moving frame 22 and the intermediate vertical plate 20.
As a result, the suspension means 35 for moving the support plate 13 substantially parallel to the opening end surface (moving the support plate 13 in a horizontal direction orthogonal to the moving direction of the moving frame 22 in plan view) is interposed.

In order to move the moving frame 22 at right angles to the front face, the moving frame 2 in the link mechanism 28 is required.
It is preferable that the point of application of the force to position 2 (the position of the pin 32) be located at the approximate center of the frontage dimension of the movable frame 22 as much as possible. In addition, for an exhibition device having a wide frontage, it is preferable that the link mechanism 28 shown in FIG.

Is in sliding contact with the lower surface of the fixed rail 35a, and the sliding member 38, which is also provided on the surface of the intermediate rail 35b, is in sliding contact with the upper surface of the moving rail 35c. The intermediate rail 35b is configured to withstand a lateral load applied in a direction perpendicular to the longitudinal direction (in other words, in the thickness direction of each rail) and to be hard to come off the moving rail 35c and the fixed rail 35a.

An urging means 16 is interposed between the support 13 and the intermediate vertical plate 20 for elastically urging the upper end of the back plate 6 above the support 13 toward the opening end face. Let it. As one embodiment of the urging means 16, the support 13 is connected to the lower end of the outer surface of the intermediate vertical plate 20 via a hinge 37 so that the upper end of the upper rear plate 6 contacts the opening end surface. It is pivotally mounted so that it can be released. The hinge body 37 is composed of a pair of mounting pieces made of an extruded aluminum material, and a notched cylindrical body that rotatably holds the base ends (lower ends) of the mounting pieces. The hinge body 37 also has the frontage dimension H1. It is formed almost as long as.

Above the hinge body 37, the entire back plate 6 is supported as an elastic biasing body for biasing the upper end thereof at an angle θ1 with respect to a vertical line in the direction of the opening end face of the opening. A screw shaft 40 protruding from the reinforcing frame 39 on the back surface of the body 13 is protruded through a through hole formed in the intermediate vertical plate 20, and a nut 41 is screwed onto the screw shaft 40.
1 and the back surface of the intermediate vertical plate 20, a compression coil spring 42 as an elastic biasing member is inserted between the support member 13 and the intermediate vertical plate 20.
It is attracting and urging so as to approach. Therefore, by adjusting the screwing position of the nut 41 with respect to the screw shaft 40, the inclination angle θ1 shown in FIG. 6 can be adjusted to adjust the attraction force (sealing pressure). The rubber piece 43 fitted on the screw shaft 40 and disposed between the reinforcing frame 39 and the intermediate vertical plate 20 is a buffer member.

FIGS. 3, 4 and 7 show that the function of the seismic isolation device is stopped in synchronism with the operation of moving the moving wall when exchanging exhibits or the like, and conversely, the state of functioning is guaranteed. Locking means 55 for locking and unlocking the upper base body via a base frame so that
It is. The locking means 55 is operated to lock and unlock the moving means 14 arranged in the upper base body 9 in synchronization with the operation of the driving means 15 for separating and approaching the opening. It is linked as follows.

Next, the locking means 55 and an interlocking mechanism for synchronizing the locking means 55 with the operation of the driving means 15 will be described in detail. In the present embodiment, a transmission box 45 such as a bevel gear as an interlocking mechanism is arranged at the tip of the screw rod 27 and on the side near the handle 29. Each transmission box 45 is fixed to the lower surface of the connecting member 26. FIG. 7 is a cross-sectional view of the transmission box 45 on the side close to the handle 29. In the transmission box 45, a bevel gear 56 fixed to the end of the threaded rod 27 is fixed to the upper end of the longitudinal axis 57. 58 are arranged so as to mesh with each other. A bevel gear 60 is also fixed to an end of a rotating shaft 59 rotated by the handle 29.

The lower end of the longitudinal axis 57 and the vertical screw shaft 46 below the lower end are fixed with screws 62, 62 via a connecting pipe 61. This is a configuration for simplifying maintenance such as inserting and extracting the lower lock rod 47 at a predetermined position without disassembling the transmission box 45. The lock rod 47 has a non-circular flat cross section, and is screwed to a lower portion of the screw shaft 46. However, the lock rod 47 cannot fall off at the lower end of the screw shaft 46. Further, a compression spring 63 is disposed between the screw shaft 46 and the inner diameter of the lock rod 467 to urge the lock rod 47 itself downward to prevent play of the threaded portion.

On the upper base body 9, four horizontal members (only three members 9b, 9c and 9d are shown in FIG. 7) are fixed by welding, so that the lock rod 47 guides only the vertical movement without rotating. Similarly, four horizontal members (only three members 10b, 10c and 10d are shown in FIG. 7) are fixed to the base frame (lower base body) 10 by welding. Accordingly, an engagement hole 49 is formed in which the lock rod 47 can be fitted only in the vertical movement without rotating.

Therefore, by the operation of the driving means 15 (rotation of the handle 29), each of the vertical screw shafts 46 rotates forward through the transmission boxes 45 when the screw rod 27 rotates forward.
The non-circular lock rod 47 screwed to the lower end is non-rotatably guided by the guide hole 48 of the upper base body 9 and descends, and fits into the engagement hole 49 formed in the base frame (lower base body) 10. And lock it (see FIGS. 3 and 4).

With this, the operator can fix the upper base body 9 to the base frame 10 simultaneously with the operation of pushing out the support 13 (opening the back plate 6) by the operation of the driving means 15, so that one operation is performed. In addition to performing the two operations at the same time, it is possible to secure the operation of stopping the upper base body 9 at the time of taking in and out the exhibits, and to safely handle the articles on the upper base body 9.

Conversely, when the handle 29 is rotated in the reverse direction, the screw rod 27 rotates in the reverse direction, and in synchronization with the operation of pushing the support 13 into the upper base body 9, the respective vertical screws are transmitted through the transmission boxes 45, 45. Since the shaft 46 rotates in the reverse direction, when the lock rod 47 is lifted and its lower end is disengaged from the engagement hole 49 of the base frame 10, the lock can be released. In this manner, the seismic isolation device 8 can automatically function when the backing plate 6 is closed after finishing the work of taking in and out the exhibits, so that the problem of forgetting to unlock as in the related art can be solved. is there.

As another modified example of the driving means 15, a spring means for urging the moving frame 22 into the upper base body 9 via a link mechanism of another form or directly is provided. When the moving frame 22 is connected to the upper base body 9 via a gas spring cylinder and the gas spring cylinder is operated, the moving frame 22 is moved from the upper base body 9 against the urging force of the spring means. The moving frame 22 may be configured to be pushed out in a direction in which the moving frame 22 is moved, or may be driven so as to directly move back and forth (advance and retreat) by an electric actuator or a pneumatic actuator that operates linearly. Furthermore, a pinion gear that meshes with a rack fixed along the support arm member 22a may be driven by an electric motor that can rotate forward and reverse.

As a means for operating the lock rod 47 in the locking and unlocking directions, a spring biasing means is used in the locking direction instead of the screw-type interlocking mechanism, and the spring biasing means is used in the unlocking direction. Using an electromagnetic solenoid that pushes up the lock rod 47 against the urging force of the urging means,
A structure is adopted in which the lock rod 47 is raised and lowered by an electric motor capable of rotating forward and reverse, and the switch of the driving means 15 is turned ON / OFF.
An electromagnetic solenoid or an electric motor may be operated by an OFF signal.

In order to keep the temperature and / or humidity of the air in the exhibition space on the base 2 constant, an air conditioner (air conditioner) 50 is disposed in the upper base body 9 and the conditioned air is supplied. , The upper floor plate 7 and the mounting table 5
Air is introduced into the exhibition space through air holes (not shown) formed in each of the air conditioners 1 (see FIG. 5).

Next, the operation of the back plate 6 having the above configuration will be described. When the movable frame 22 is retracted (when the movable frame 22 is retracted toward the upper base body 9), the compression coil spring 42 as a biasing means between the intermediate vertical plate 20 and the support 13 is screwed. Via the shaft 40, the support 1
3 is urged to pull in, the support 13
The rear plate 6 erected from the bottom is in close contact with the packing 44 on the opening end face of the opening, so that the exhibition space on the base 2 can be hermetically sealed (see the state of FIG. 5).

The back plate 6 closing the exhibition space
First, the lock of the open / close door 12 on one side of the base 2 is unlocked and opened, and when the handle 29 is turned in one direction, the nut member 33 screwed to the screw rod 27 that rotates in the forward direction is opened. The direction of the pin 30 is approached, and the other link piece 28b is pushed by the other link piece 28b, and the moving frame 22 is moved rearward from the upper base body 9 (outside of the rear face, FIG. 1 and FIG. (In the direction of arrow A), and the link mechanism 2 is moved so that the support 13 and the back plate 6 are separated from the opening end face.
8 is activated. At this time, the lock rod 47 is simultaneously lowered via the transmission box 45, and the upper base body 9 and the base frame 1 are moved.
Lock both so that they do not move relative to each other. This makes it possible to safely and reliably carry out the work of putting in and out the exhibits, which will be described later, and placing the work.

On the outer surface of the vertical plate 21 of the moving frame 22 which is pushed out (projected) by L1 (arbitrary amount) from the back surface of the upper base body 9, a fixed rail 35a in the suspension rail device is provided with a width H1 of the width H1. The intermediate rail 35b having the same length is fixed to the intermediate rail 35b, and the intermediate rail 35b has the same length as the intermediate rail 35b. Since it is fixed, the intermediate vertical plate 20 can be moved in the frontage direction. In this type of suspension rail device, the intermediate rail 35b can protrude from the distal end of the fixed rail 35a to approximately half the length of the intermediate rail 35b. Since the moving rail 35c can protrude to the length of the fixed rail 35a, the moving rail 35c can protrude to a length of about 90% or more.

Accordingly, when the operator pushes the support 13 or the back plate 6 in the direction of the arrow B in FIG. 1 or FIG. 2, the support 13 provided on the outer surface of the intermediate vertical plate 20 has the dimension of the frontage. By moving by a distance substantially equal to H1, almost the entire opening of the exhibition space can be greatly opened, and the work of putting in and taking out the exhibition object with respect to the exhibition apparatus 1 becomes extremely easy.

As shown in FIG. 6, when the movable frame 22 is pushed out, the back plate 6 erected from the support 13 disposed on the outer surface of the movable frame 22 separates from the packing 44 on the opening end face of the opening. , Airtightness can be released.

To close the back plate 6, an operator pushes the support 13 or the back plate 6 back in the direction of the arrow C in FIG. 1 or FIG. 2 so that the back plate 6 is closed by the packing 44 on the opening end face of the opening. When the handle 29 is rotated in the opposite direction at the position overlapping the location, the moving frame 22 is pulled into the upper base body 9 by the reverse operation. In a free state in which the back plate 6 is not in contact with the packing 44 on the opening end face of the opening, the upper end side of the back plate 6 approaches the packing 44 on the opening end face by θ1 from the vertical line by the urging means 16. The upper end side of the back surface of the back plate 6 first comes into contact with the packing 44 in response to the retraction of the moving frame 22, and then gradually the support 13 side (the lower side of the back surface of the back plate 6). Is brought into contact with the packing 44 and when the drawing is completed, the upper and lower surfaces of the back surface of the back plate 6 can be tightly sealed.

As described above, the support 1 on which the back plate 6 is erected is provided.
The airtightness of the opening can be improved by interposing the urging means 16 between the moving means 3 and the moving means 14 so that the back plate 6 can elastically press the opening end face of the opening. The air-conditioning effect on the exhibits in the designated exhibition space can be enhanced.

When the entire back surface of the back plate 6 is in close contact with the packing 44, the end surface of the nut 41 screwed to the screw shaft 40 is configured to contact the back surface of the intermediate vertical plate 20. Then, the back plate 6 and the packing 44
The back plate 6 cannot be shaken or moved so as to generate a gap between the back plate 6 and the space between the back plate 6 and the airtightness.

The upper end of the back plate 6 in the free state is urged by the urging means 16 formed by the hinge 37, the screw shaft 40 and the compression coil spring 42 interposed between the intermediate vertical plate 20 and the support 13. If it is tilted in the direction approaching the packing 44 of the opening end face by θ1 from the vertical line in advance, even if there is an installation error due to the moving frame 22 or the suspension rail device or a tilt error of the movement with respect to the horizontal, the opening end face at the time of closing is closed. , It is easy to secure airtightness of the entire back plate 6, particularly the upper end side.

The present invention can also be applied to a device in which one of the side plates or the front plate 4 is used as a moving wall instead of the back plate 6, and is also applied to a display device in which side plates are arranged in a hexagonal or octagonal plane. it can. In another embodiment, the urging means 16 is not interposed, so that the outer surface of the vertical plate 21 and the support 13
By interposing the suspension rail device directly between the rear plate and the rear surface of the vehicle, the rear plate 6 may be opened greatly in the frontage direction.

Further, the moving means 14 moves the support 13
It goes without saying that the present invention can be applied not only to a device that moves forward and backward in parallel with the back surface (front surface) and the like of the upper base body 9 but also to a device that moves forward and backward while swinging and rotating non-parallel. .

[0049]

As described above, in the display device according to the first aspect of the present invention, the upper base body in the display device is
At least a side formed by a fixed wall surrounding the exhibition space on the upper base body and an open edge of the fixed wall, which is mounted on the base frame fixed to the floor via the seismic isolation device so as to be laterally movable. A moving wall for opening and closing the opening, a support for supporting a lower end of the moving wall, and the support in a direction in which the moving wall comes into contact with and separates from the upper base body with respect to the opening. And a locking means for locking the upper base body via a base frame.

According to this configuration, prior to the operation of moving the moving wall to open the opening, the upper base body is locked to the base frame by the locking means, and then the moving wall is moved. It is possible to prevent an accident such as an exhibit on the upper base body from swaying, falling over, and being damaged with the work of taking in and out of articles. Conversely, it is only necessary to release the lock after the work of taking in and out the exhibit so that the function of the seismic isolation device can be exhibited.

According to a second aspect of the present invention, in the display apparatus according to the first aspect, the moving means is configured to move in the contact / separation direction by a driving means provided in the upper base body. The locking means is operated so as to lock and unlock the locking means in synchronization with the operation of the driving means for moving the moving means apart from and approaching the opening.

As described above, by synchronizing the operation of the driving means and the operation of the locking means, it is possible to prevent the upper base body from being inadvertently moved during the loading / unloading operation of articles.
The present invention has an effect that it is possible to surely prevent breakage of the display object, and to eliminate an accident that the user forgets to release the lock after finishing the work of taking in and out the article.

The third aspect of the present invention is the first aspect of the present invention.
Alternatively, the display device according to claim 2, further comprising a suspension means at a tip of the moving means for guiding the support in a direction intersecting the moving direction of the moving means in a plan view. . By moving the moving wall largely in the lateral direction of the opening via the suspension means in this manner, the exhibition space can be largely opened, and the work of putting in and out the exhibits can be performed safely. On the other hand, the moving wall protrudes greatly from the upper base body,
Since the center of gravity is deviated, the seismic isolation device becomes easier to work, and the upper base body easily moves laterally. In this case, if locking is possible, the upper base body can be more securely stopped.

It is connected by. The tip of the other link piece 28b pivotally connected to the nut member 33 screwed to the screw rod 27 by a pin is pivotally connected to a middle part of the one link piece 28a.

Between the outer surface of the vertical plate 21 fixed to the moving frame 22 and the intermediate vertical plate 20, the intermediate vertical plate 20 is provided.
As a result, the suspension means 35 for moving the support plate 13 substantially parallel to the opening end surface (moving the support plate 13 in a horizontal direction orthogonal to the moving direction of the moving frame 22 in plan view) is interposed.

In order to move the moving frame 22 at right angles to the frontage surface, the moving frame 2 in the link mechanism 28 is required.
It is preferable that the point of application of the force to position 2 (the position of the pin 32) be located at the approximate center of the frontage dimension of the movable frame 22 as much as possible. In addition, for an exhibition device having a wide frontage, it is preferable that the link mechanism 28 shown in FIG.

Then, between the upper and lower linear longitudinal guide grooves on the fixed rail 35a and the upper and lower surfaces of the upper linear longitudinal ridge 36a on the intermediate rail 35c, and on the movable rail 35c. The lower linear elongate ridge 36 on the intermediate guide rail and the intermediate rail 35c
b, bearing balls held by retainers are interposed between the upper and lower surfaces in a row, and the support 13 (back plate 6) is moved along with the intermediate vertical plate 20 along the frontage direction with a light force. It is configured to be movable.

A long sliding member 38 having a small coefficient of friction, such as nylon resin, protruding from the back surface of the intermediate rail 35b.
Is in sliding contact with the lower surface of the fixed rail 35a, and the sliding member 38, which is also provided on the surface of the intermediate rail 35b, is in sliding contact with the upper surface of the moving rail 35c. The intermediate rail 35b is configured to withstand a lateral load applied in a direction perpendicular to the longitudinal direction (in other words, in the thickness direction of each rail) and to be hard to come off the moving rail 35c and the fixed rail 35a.

An urging means 16 is interposed between the support 13 and the intermediate vertical plate 20 to elastically urge the upper end of the back plate 6 above the support 13 toward the opening end face. Let it. As one embodiment of the urging means 16, the support 13 is connected to the lower end of the outer surface of the intermediate vertical plate 20 via a hinge 37 so that the upper end of the upper rear plate 6 contacts the opening end surface. It is pivotally mounted so that it can be released. The hinge body 37 is composed of a pair of mounting pieces made of an extruded aluminum material, and a notched cylindrical body that rotatably holds the base ends (lower ends) of the mounting pieces. The hinge body 37 also has the frontage dimension H1. It is formed almost as long as.

[0026] The upper position than the hinge member 37, as resilient biasing member for urging tilted close angle θ1 with respect to the vertical line the back plate 6 to the opening end face direction of the upper side the opening, A screw shaft 40 protruding from the reinforcing frame 39 on the back surface of the support 13 is protruded through a through hole formed in the intermediate vertical plate 20, and a nut 41 is screwed onto the screw shaft 40, and is interposed with the nut 41. A compression coil spring 42 serving as an elastic urging member is interposed between the vertical plate 20 and the back surface thereof to attract and urge the support 13 to approach the intermediate vertical plate 20.
Therefore, by adjusting the screwing position of the nut 41 with respect to the screw shaft 40, the inclination angle θ1 shown in FIG. 6 can be adjusted to adjust the attraction force (sealing pressure). The rubber piece 43 fitted on the screw shaft 40 and disposed between the reinforcing frame 39 and the intermediate vertical plate 20 is a buffer member.

FIGS. 3, 4 and 7 show that the function of the seismic isolation device is stopped in synchronism with the operation of moving the moving wall when exchanging exhibits or the like, and conversely, the state of functioning is guaranteed. Locking means 55 for locking and unlocking the upper base body via a base frame so that
It is. The locking means 55 operates to lock and unlock in synchronization with the operation of the driving means 15 for separating and approaching the moving means 14 disposed in the upper base body 9 with respect to the opening. It is linked as follows.

Next, the locking means 55 and an interlocking mechanism for synchronizing the locking means 55 with the operation of the driving means 15 will be described in detail. In the present embodiment, a transmission box 45 such as a bevel gear as an interlocking mechanism is arranged at the tip of the screw rod 27 and on the side near the handle 29. Each transmission box 45 is fixed to the lower surface of the connecting member 26. FIG. 7 is a cross-sectional view of the transmission box 45 on the side close to the handle 29. In the transmission box 45, a bevel gear 56 fixed to the end of the threaded rod 27 is fixed to the upper end of the longitudinal axis 57. 58 are arranged so as to mesh with each other. A bevel gear 60 is also fixed to an end of a rotating shaft 59 rotated by the handle 29.

The lower end of the longitudinal axis 57 and the vertical screw shaft 46 thereunder are fixed with screws 62, 62 via a connecting pipe 61. This is a configuration for simplifying maintenance such as inserting and extracting the lower lock rod 47 at a predetermined position without disassembling the transmission box 45. The lock rod 47 has a non-circular flat cross section, and is screwed to a lower portion of the screw shaft 46. However, the lock rod 47 cannot fall off at the lower end of the screw shaft 46. Further, a compression spring 63 is disposed between the screw shaft 46 and the inner diameter of the lock rod 467 to urge the lock rod 47 itself downward to prevent play of the threaded portion.

The upper base body 9 is fixed by welding four horizontal members (only three members 9b, 9c and 9d are shown in FIG. 7), so that the lock rod 47 does not rotate but only moves up and down. Guide holes 48 capable of guiding are formed, and similarly, four horizontal members (only three members 10b, 10c and 10d are shown in FIG. 7) are fixed to the base frame (lower base body) 10 by welding. Thus, an engagement hole 49 is formed in which the lock rod 47 can be fitted only by non-rotation and vertical movement.

Accordingly, by the operation of the driving means 15 (rotation of the handle 29), each of the vertical screw shafts 46 rotates forward through the transmission boxes 45 when the screw rod 27 rotates forward.
The non-circular lock rod 47 screwed to the lower end is non-rotatably guided by the guide hole 48 of the upper base body 9 and descends, and fits into the engagement hole 49 formed in the base frame (lower base body) 10. And lock it (see FIGS. 3 and 4).

By this, the operator can fix the upper base body 9 to the base frame 10 simultaneously with the operation of pushing out the support 13 (opening the back plate 6) by the operation of the driving means 15, so that two operations can be performed in one operation. In addition to performing the two operations at the same time, it is possible to secure the operation of stopping the upper base body 9 at the time of taking in and out the exhibits, and to safely handle the articles on the upper base body 9.

Conversely, when the handle 29 is rotated in the reverse direction, the screw rod 27 rotates in the reverse direction, and in synchronization with the operation of pushing the support 13 into the upper base body 9, the respective vertical screws are transmitted via the transmission boxes 45, 45. Since the shaft 46 rotates in the reverse direction, when the lock rod 47 is lifted and its lower end is disengaged from the engagement hole 49 of the base frame 10, the lock can be released. In this manner, the seismic isolation device 8 can automatically function when the backing plate 6 is closed after finishing the work of taking in and out the exhibits, so that the problem of forgetting to unlock as in the related art can be solved. is there.

As another modified example of the driving means 15, a spring means for urging the moving frame 22 in the direction of pulling the moving frame 22 into the upper base body 9 via a link mechanism of another form or directly is provided. When the moving frame 22 is connected to the upper base body 9 via a gas spring cylinder and the gas spring cylinder is operated, the moving frame 22 is moved from the upper base body 9 against the urging force of the spring means. The moving frame 22 may be configured to be pushed out in a direction in which the moving frame 22 is moved, or may be driven so as to directly move back and forth (advance and retreat) by an electric actuator or a pneumatic actuator that operates linearly. Furthermore, a pinion gear that meshes with a rack fixed along the support arm member 22a may be driven by an electric motor that can rotate forward and reverse.

As a means for operating the lock rod 47 in the locking and unlocking directions, a spring biasing means is used in the locking direction instead of the screw-type interlocking mechanism, and the spring biasing means is used in the unlocking direction. Using an electromagnetic solenoid that pushes up the lock rod 47 against the urging force of the urging means,
A structure is adopted in which the lock rod 47 is raised and lowered by an electric motor capable of rotating forward and reverse, and the switch of the driving means 15 is turned ON / OFF.
An electromagnetic solenoid or an electric motor may be operated by an OFF signal.

In order to keep the temperature and / or humidity of the air in the exhibition space on the base 2 constant, an air conditioner (air conditioner) 50 is arranged in the upper base body 9 to supply the conditioned air. , The upper floor plate 7 and the mounting table 5
Air is introduced into the exhibition space through air holes (not shown) formed in each of the air conditioners 1 (see FIG. 5).

Next, the operation of the back plate 6 having the above configuration will be described. When the movable frame 22 is retracted (when the movable frame 22 is retracted toward the upper base body 9), the compression coil spring 42 as a biasing means between the intermediate vertical plate 20 and the support 13 is screwed. Via the shaft 40, the support 1
3 is urged to pull in, the support 13
The rear plate 6 erected from the bottom is in close contact with the packing 44 on the opening end face of the opening, so that the exhibition space on the base 2 can be hermetically sealed (see the state of FIG. 5).

The back plate 6 closing the exhibition space
First, the lock of the open / close door 12 on one side of the base 2 is unlocked and opened, and when the handle 29 is turned in one direction, the nut member 33 screwed to the screw rod 27 that rotates in the forward direction is opened. The direction of the pin 30 is approached, and the other link piece 28b is pushed by the other link piece 28b, and the moving frame 22 is moved rearward from the upper base body 9 (outside of the rear face, FIG. 1 and FIG. (In the direction of arrow A), and the link mechanism 2 is moved so that the support 13 and the back plate 6 are separated from the opening end face.
8 is activated. At this time, the lock rod 47 is simultaneously lowered via the transmission box 45, and the upper base body 9 and the base frame 1 are moved.
Lock both so that they do not move relative to each other. Safely and reliably perform the loading and unloading operations and placing operations of the exhibit to be described later from <br/> to be this.

On the outer surface of the vertical plate 21 of the moving frame 22 which is pushed out (projected) by L1 (arbitrary amount) from the back surface of the upper base body 9, a fixed rail 35a in the suspension rail device is provided with a width H1 of the width H1. The intermediate rail 35b having the same length is fixed to the intermediate rail 35b, and the intermediate rail 35b has the same length as the intermediate rail 35b. Since it is fixed, the intermediate vertical plate 20 can be moved in the frontage direction. In this type of suspension rail device, the intermediate rail 35b can protrude from the distal end of the fixed rail 35a to approximately half the length of the intermediate rail 35b. Since the moving rail 35c can protrude to the length of the fixed rail 35a, the moving rail 35c can protrude to a length of about 90% or more.

Accordingly, when the operator pushes the support 13 or the back plate 6 in the direction of the arrow B in FIG. 1 or FIG. 2, the support 13 provided on the outer surface of the intermediate vertical plate 20 has the size of the frontage. By moving by a distance substantially equal to H1, almost the entire opening of the exhibition space can be greatly opened, and the work of putting in and taking out the exhibition object with respect to the exhibition apparatus 1 becomes extremely easy.

As shown in FIG. 6, when the moving frame 22 is pushed out, the back plate 6 erected from the support 13 disposed on the outer surface of the moving frame 22 separates from the packing 44 on the opening end face of the opening. , Airtightness can be released.

To close the back plate 6, an operator pushes the support 13 or the back plate 6 back in the direction of arrow C in FIG. 1 or FIG. 2 so that the back plate 6 is closed by the packing 44 on the opening end face of the opening. When the handle 29 is rotated in the opposite direction at the position overlapping the location, the moving frame 22 is pulled into the upper base body 9 by the reverse operation. In a free state in which the back plate 6 is not in contact with the packing 44 on the opening end face of the opening, the upper end side of the back plate 6 approaches the packing 44 on the opening end face by θ1 from the vertical line by the urging means 16. The upper end side of the back surface of the back plate 6 first comes into contact with the packing 44 in response to the retraction of the moving frame 22, and then gradually the support 13 side (the lower side of the back surface of the back plate 6). Is brought into contact with the packing 44 and when the drawing is completed, the upper and lower surfaces of the back surface of the back plate 6 can be tightly sealed.

As described above, the support 1 on which the back plate 6 is erected
The airtightness of the opening can be improved by interposing the urging means 16 between the moving means 3 and the moving means 14 so that the back plate 6 can elastically press the opening end face of the opening. The air-conditioning effect on the exhibits in the designated exhibition space can be enhanced.

When the entire back surface of the back plate 6 is in close contact with the packing 44, the end surface of the nut 41 screwed to the screw shaft 40 is configured to contact the back surface of the intermediate vertical plate 20. Then, the back plate 6 and the packing 44
The back plate 6 cannot be shaken or moved so as to generate a gap between the back plate 6 and the space between the back plate 6 and the airtightness.

The upper end of the back plate 6 in the free state is urged by the urging means 16 interposed between the intermediate vertical plate 20 and the support 13 by the hinge 37, the screw shaft 40 and the compression coil spring 42. If it is tilted in the direction approaching the packing 44 of the opening end face by θ1 from the vertical line in advance, even if there is an installation error due to the moving frame 22 or the suspension rail device or a tilt error of the movement with respect to the horizontal, the opening end face at the time of closing is closed. , It is easy to secure airtightness of the entire back plate 6, particularly the upper end side.

The present invention can also be applied to a case where one side plate or the front plate 4 is used as a moving wall instead of the back plate 6, and is also applied to an exhibition device having hexagonal or octagonal side plates arranged in a plane. it can. In another embodiment, the urging means 16 is not interposed, so that the outer surface of the vertical plate 21 and the support 13
By interposing the suspension rail device directly between the rear plate and the rear surface of the vehicle, the rear plate 6 may be opened greatly in the frontage direction.

Further, the moving means 14 moves the support 13
It goes without saying that the present invention can be applied not only to a device that moves forward and backward in parallel with the back surface (front surface) and the like of the upper base body 9 but also to a device that moves forward and backward while swinging and rotating non-parallel. .
